If you use a smaller screen, one screen per plant, and attach it to the pot, you can ScroG and still retain the ability to move your plants around individually. All it takes is a pair of wire cutters, some clothes hangars, and some duct tape.

What works good for screens are those wire basket clothes organizers they sell at Home Depot. You can clip one of those down to one large screen (~2 square feet) or two smaller ones (~1 square foot each). They make very sturdy screens which require no additional support and can be bent if you need to bend them.
